Origin: After graduation, Jennifer Wilson married her high school sweetheart, Kevin Murphy. He seemed nice and she thought that was all that mattered. He was a footbal star, she was a cheerleader. It seemed perfect. It was a while before he started hitting Jennifer.
Kevin worked for his dad as an electrician, hated it, and he'd take his frustration out on her.
Jennifer thought having a child might help but when they had a daughter that they named Angelica it only seemed to make matters worse.
One day, it stopped hurting. Jennifer didn't know why. She thought she was just blocking out the pain, that she was numb to it. It wasn't until later that she realized that these were the first signs of dormant mutant powers being triggered. It frustrated Kevin that she wasn't reacting the way she used to. It wasn't as satisfying as it had been.
One day, in frustration, he tried to take it out on Angel. When Jennifer tried to protect her child she hit him. His exploded. The rest of Jennifer's superpowers had kicked in.
There was a trial. A man known only as "Grundy" tried to pin a string of murders on Jennifer that a vigilante supervillain known as Guillotine had commited. Officer Dragon of the Chicago Police stood by her through the ordeal. He found the real murderer and arrested her. The charges were dropped against Jennifer and she was reunited with her daughter Angel.
A few months afterwards, following the failed Martian Invasion of Earth, Dragon was recruited by the U.S. Government to head up a superhuman strike force to prevent other major catastrophes. Jennifer, code named "Smasher," accepted his offer to join the team, called 'Special Operatives Strikeforce.' So adept at using her vast strength in physical combat, she quickly sped her way through recruit training to become a core member of the team.
On the team's first major mission, Smasher and Dragon were marooned on and later escaped the doomed planet Darkworld, and on a several-month long oddesey found their way to a bizarre planet where they did battle with mythological Gods. Eventually, Dragon and Smasher were returned to Earth and to her daughter - and perhaps to the beginnings of a romantic relationship.
